Anterior Triangle of Neck

Boundaries

BASE: Body of mandible and the line joininig the angle of mandible to mastoid process POSTERIORLY: Anterior border of Sternocleidomastoid muscle ANTERIORLY: Median plane of the neck APEX: Manubrium sterni

Subdivision

Submental Digastric Carotid Muscular

Contents of Ant. Triangle ARTERY: 1.External & Internal carotid artery 2. Occipital artery 3. Facial artery 4. Lingual & 5. Sup. Thyroid artery VEIN: 1. Internal jugular 2. External jugular Submandibular gland Accessory nerve Vagus nerve Suprahyoid & infrahyoid muscle

Posterior Triangle 0f Neck

Boundaries & Subdivisions• Boundaries: • Anteriorly posterior border of the

Sternocleidomastoid • Posteriorly anterior border of trapezius• Apex is the meeting point of

sternocleidomastoid and trapezius• Base is the medial one third of the

clavicle• Roof is skin , superficial fascia and deep

fascia• Floor is the prevartebral layer of deep

cervical fascia

Subdivision : 1. Occipital triangle 2. Supraclavicular triangle

Contents of Posterior triangle

NERVES: 1.Lesser occipital 2. Great auricular 3. Ant. Cutaneous4. Supraclavicular5.Mascular branches6. Trunks of brachial plexusVESSEL:1.Transverse cervical artery 2. Occipital artery LYMPH NODES

Submandibular RegionThe area between the body of mandible and the hyoid bones is known as submandibular regionBOUNDARIES: Superiorly mylohyoid muscle ,

inferior border of mandible Inferiorly anterior and

posterior belly of digastric Laterally deep cervical fascia ,

platysma Medially hypoglossus Anteriorly submental space Posteriorly hyoid bone

Contents of submandibular region

1. Submandibular salivary gland

2. Proximal portion of Submandibular duct

3. Lingual and hypoglossal nerve

4. Branches of facial artery paletine, tonsillar glandular branch

Clinicals

1. The most common location for atherosclerotic plaque formation is at the bifurcation or branch points of arteries, in the case of the carotid arteries

2.  bruit is a systolic murmur heard only in the neck arteries

3. Tracheostomy a surgical procedure to create an opening through the neck into the trachea 

4. Carotid sinus syndrome
